The current season of Celebrity Apprentice has been surprisingly entertaining, given that two-hour episodes are almost always a bad idea on reality shows. But there’s a sadness hovering over the season, a sense that this could be the end of the good times. And no, it’s got nothing to do with the rumors that Donald Trump is going to run for President (he won’t, by the way) – it’s the feeling that they may have finally run out of zanies to cast. How do you go on after Star Jones, Gary Busey, and Meat Loaf?

At any rate, Trump has now gone and done something I did not see coming, which is to fire Busey. I had just assumed he had been pre-selected to win this thing in the same way Joan Rivers and Bret Michaels were. So who knows what to think now, as we enter the home stretch of the season (NBC, Sunday 9 p.m.)? The task this week is creation of an ad campaign for the Trump Hotel Collection, and word has it that the Star/Nene Leakes rivalry will again boil over. My best guess is that Star and Meat Loaf will battle it out in the final boardroom of the season, with Trump going with the people’s choice to win, Mr. Bat Out of Hell.

Also this week:

Monday: Bethenny Ever After (Bravo, 10 p.m.): For someone who claims not to want to be a reality star, Bethenny is making a run at the record for most different series having been a part of. This week, we revisit all the drama surrounding her appearance on yet another show, Skating With the Stars, which we’re led to believe ruined her entire holiday season. Boo and Hoo.

Tuesday: 16 and Pregnant (MTV, 10 p.m.): A third season begins, and with it a whole new batch of girls who might once have been told that this baby will ruin their lives, but now can look forward to spending the next several years on magazine covers.This week, a teen reacts badly when she feels her twin sister is putting her baby and baby daddy ahead of her. The nerve of some people.

Wednesday: Modern Family (ABC, 9 p.m.): Mitchell and Cameron try to decide on who would make a suitable guardian for Lily should something unpleasant happen to them, but they begin to wonder if the most obvious candidates, Claire and Phil, are really up to the task when they take a good look at what their own kids have been up to.

Thursday: Bones (Fox, 9 p.m.): A security guard at a maritime museum turns up dead in the Everglades, and Brennan and Booth seek help on the case from a former soldier in Iraq (Geoff Stults) who has acquired the ability to magically locate things.

Friday: CHAOS (CBS, 8 p.m.): The agents learn that a spy who was once Casey’s girlfriend has had her cover blown while on assignment in China, but once she tells them she’s tracking a terrorist, they decide to give her a hand instead of getting her out of there. Sounds positively CHAO-tic.

Saturday: Cinema Verite (HBO, 9 p.m.): Have we discovered our Grey Gardens or Temple Grandin for 2011? This film tells the tale of the pioneer of reality television, a producer (James Gandolfini) who hits on the idea of filming a normal American family for several months in the early 1970s, and seeing what happens (as everyone watching today yells “Don’t do it!” at the screen). Tim Robbins and Diane Lane play the parents.
